Be it known that I, .HENRY W.MERRITT, the usual manner.of Somerville, in the county of Middlesex and This carbureter can beused for carbureting State of Massachusetts, have invented a new withair or coal-gas, as may be desired. and useful improvement inGarbureters, of On the annexed drawings, Figure l reprewhich thefollowing is a speciiication: sents a-central longitudinal section of myin- My `invention relates to improvements on .vention.
